Mike has it correct, the one set is backwards and I might add mounted closer in. BTW, yes I know that the 70 used a narrower bracket set for the fenders than did the 100 (Thanks to Paul Bell for that bit of info on the 70 vs 100 fender brackets he posted a while back). However, the fenders are mounted even closer in than those brackets would mount them. Looks like the wheels on that one are reversed for a narrow track as well. The bent up fenders on the Original are either home made or adapted from something else.
